KEY POINTS:
A small snippet of Ghostbusters music was the sole musical note at the Act Party conference.
It was slightly altered to become "Growth Busters" as the party criticised Labour Party policies and their effect on New Zealand's economic growth.
However, Eminem's Without Me may have been a more
apt choice because, as the lyrics go, "guess who's back, back again?"
It's Sir Roger Douglas because - again as the song goes - "we need a little controversy and it feels so empty without me".
Sir Roger made his first official appearance alongside the Act Party at its conference over the weekend.
His first job was to confirm speculation he would stand for the party in this year's election - nearly 40 years after he first entered Parliament in 1969.
Should he actually get back into the House it will be his first time as an MP for Act - the party he set up himself after retiring in 1990.
Others in the party affectionately call the 70-year-old "the Pensioner", but defend it by pointing to John McCain and Ronald Reagan.
Sir Roger himself scoffed at the "too old" suggestion, pointing out he was only one month older than his nemesis Progressives leader Jim Anderton - "and I was always better than him anyway".
However, his return after quitting the party in 2003 in disgust at its muck-raking ways under Rodney Hide certainly put about 200 delegates at the conference in a good mood.
Business Roundtable buddy Roger Kerr and Act's former president and fellow BRT member Catherine Judd were there to cheer his reincarnation on, as well as John Ansell - the ad man who created National Party billboards and the television Taxathon ads before the last election.
The brain drain and gap between Australia and New Zealand were the underlying themes of the conference, alongside Act's message that National's and Labour's policies are so similar that Act will be needed to push National around after the election.
Sir Roger emphasised the different standard of living in Australia compared to New Zealand, saying even Tasmanians earned $100 per week more than the average New Zealander.
"When I grew up we felt sorry for Tasmania. Unfortunately, we have become Tasmania's poor cousin."
He also repeated his belief in market forces that led the 1980s deregulation of the economy, dubbed Rogernomics, when he was finance minister in the David Lange Labour government.
Mr Hide, who remains Act's leader, outlined his hopes of becoming a force in a coalition after the election and described Act as a "trim-tab" - a lever on a boat's main rudder that fine-tunes its direction.
However, it wasn't all fine sailing at the conference.
MP Heather Roy soundly condemned all other political parties for their lack of a real "vision" for New Zealand, and tried to show her own vision for the future with powerpoint slides.
Unfortunately, the technology failed to come to the party and Ms Roy's "vision" was postponed until after lunch and eventually forgotten altogether.
